Something <br> occurs when a liquid changes to a gas below its surface as well as on the surface

Every time matter changes from a liquid to a gas, the matter also experiences a change in the

Matter is predominantly know to exist in three states-

-Solid

-Liquid

-Gas

The three states can be interconverted at appropriate temperature and pressure conditions. Each state exhibits unique properties which are influenced by the intermolecular forces that hold the atoms together in these states.

Ans: Thus, Every time matter changes from a liquid to a gas, the matter also experiences a change in the <u>state (or phase)</u>

An engine cylinder contains 175 mL of gas at a pressure of 1.0 atm. As the engine runs, it compresses the cylinder, reducing the

sukhopar [10]

This problem is providing the initial volume and pressure of a gas in an engine cylinder and asks for the final pressure once the volume of the gas has decreased due to a compression. At the end, the result turns out to be 11.7 atm.

<h3>Boyle's law</h3>

In chemistry, gas laws allow us to calculate pressure, volume, temperature or moles depending on a specified change and based on the concept and equation of the ideal gas, which derives the well-known gas laws; Boyle's, Charles', Gay-Lussac's and Avogadro's.

Thus, since this problem provides initial and final volume and initial pressure for us to calculate the final pressure, we understand we need to apply the Boyle's law as a directly proportional relationship between these two:

$P_1V_1=P_2V_2$

Thus, we solve for the final pressure, P2, to get:

$P_2=\frac{P_1V_1}{V_2}=\frac{1.0atm*175mL}{15mL}\\ \\ P_2=11.7atm$

Which Act is the set of laws signed by former President Nixon that helps keep water clean in the United States?

otez555 [7]

Clean Water Act

Explanation:

The Clean Water Act in 1972 was a set of laws signed by former President Nixon that helps to keep water clean in the United States.

The act sets a safe limit for the amount and kind of pollutants that can be released into the water that won't contaminate it.
The acts charged the Environmental Protection Agency(EPA) to set a safe limit for nature and amount of pollutants that can be released into the water.
This act is one of the several environmental polices in the United States that ensures a safe drinking water is available.
